The mosaic tiles are beautiful! It's opaque glass and has flecks of light blue, slight green, muted brown and streaks of bronze/gold. It has a "mother of pearl" quality to it. It's perfect for our purposes. We are putting a wall accent (4 x 5 ft ), from the wainscotting to the ceiling on our bathroom renovation. I think it's going to provide texture without overwhelming the space. The mosaic tiles are lightweight which is handy for the install. The tiles arrived well packaged too!
